My car's topology is messing up as soon as I attempt to move a group of vertices along the y-axis
Okay, I fixed it. I had to delete most of the vertices in the middle of the car and then fill in the edges and faces. It was tedious, but I did not know any better way. The only question I have now is will using the loop cut/slide tool cause bad topology again? That is what I used and it messed up my topology, so I am wondering whether or not I should continue using that tool or if there is a better way of adding more vertices. Thanks for your help!
